Presentation Guidelines


  • If for any reason you cannot attend the conference or give your presentation, contact the conference organizers at the earliest possible time so as not to disrupt the schedule and to allow another presentation to take its place.

  • PC laptop computers will be provided by the conference in each session room. It is suggested that speakers bring their presentations on a USB stick.

  • Each room will also have one LCD projector, a laser pointer, and a microphone.

  • Presentations will run on Windows Power Point (versions from 2015-2019) with a resolution of up to 1920x1080 (via HDMI or UXGA cabling).

  • Various adapters are available upon request.

  • Only a single projector is available in the presentation rooms.

  • Please arrive and check in with the session chair and audio-visual assistant at least 15 minutes before the session begins either to load your presentation on the conference laptop or to check the connection between your computer and the projector. Note that time lost switching between computers or due to nonfunctioning computer graphics presentations will be deducted from the speaker’s allotted presentation time.

  • In general the smaller your presentation (in file size) the easier it is to handle.

  • Any movie/image file must be in the same folder as the presentation and must be copied in the folder before being included in the presentation.

  • Please direct any presentation questions to the chair for your session.

Make Sure Slides Are Simple and Legible

  • Preferred page setup is landscape orientation with high-contrast lettering and readable fonts.

  • Preferred slide layout for presentation is 16:9.

  • Use a sans serif non-stylized typeface such as Helvetica or Arial.

  • Please do not use non-standard fonts as they may not display properly or be illegible.

  • The larger the font, the better.  Avoid using anything smaller than 24-point font for text and 18 point font for labels.  Most of us can’t read too small.

  • Do not rely solely on color for contrast, but use light text on dark background or vice versa.  Some people are colorblind.

  • A maximum of 7 lines/slide and 5 words/line will improve the communication value of your slide.  Most of us can’t read fast enough for excessive content.

  • Test slides for legibility and contrast.

  • Check spelling and grammar using a spell check program or a proofreader.

  • Have an appropriate number of slides for your time.  More than one slide per presentation minute is unlikely to be understood by the audience.

  • One concept per slide is enough.

  • Include your contact information and website URL on the final slide.


Pictures and Graphics

  • Do not save pictures as .bmp or .tiff (file size is too big).

  • Images with .gif and .jpg extensions are recommended to obtain a light presentation that will load and display readily (other kinds of extensions - recognizable by PowerPoint will be accepted all the same).

  • Save the pictures used in your presentation on a USB storage as backup (in case of problems, we can re-insert the original).

  • Save the graphics or spreadsheets (Excel) used in your presentation on a separate USB-stick as back up.

  • PDFs for presentations that may have been created using a different format are acceptable.



  • Movies should not exceed 50 MB each (50 MB is not necessarily the limit; we can handle larger movies without any problems, but the video may not present as smoothly).

  • Always bring your movies on a separate USB storage as back up. The best format for videos is .mp4.




  • Poster boards cost money and space is limited.  Poster presenters are required to confirm their attendance at the conference by registration or other means.  If you have not confirmed your attendance, your poster will be removed from the program.  If for any reason you cannot attend the conference or give your poster, contact the conference organizers at the earliest possible time.

  • Posters must fit in a 3’ wide x 4’ tall space. Push pins will be available in the poster area.

  • Poster sessions are tentatively scheduled for Monday and Tuesday afternoons from 5:30 PM - 7:00 PM.

  • Please mount your poster from 2:30 – 5:00 PM on the day of the presentation.

  • Individual poster boards will be identified with poster numbers. Please check the list in the room to determine the number of your poster and mount your poster in the correct space.

  • You or a co-author are expected to be present at your poster during the entire session to answer questions.

  • Please remove your poster in a timely manner at the end of your poster session.  

  • There will be one or more prizes for the best student poster(s).
